INSULATING BRICKS FOR BACK UP LINING
Our Insulating Fire bricks, B- Series are equipped with good thermal insulation property from high porosity can prevent heat loss of furnaces and help fast elevation of temperature for fuel cost saving.
These bricks are widely used for back up lining or insulation lining of Reheating furnaces, Boiler furnaces, Aluminium melting furnaces, and general industrial furnaces.
